Troubleshooting Tip: Remote LDAP-Auth fails with connection over ConsolePort

Authentication with LDAP credentials fails when the connection to FortiADC is established via ConsolePort.

   FAD-400F-01 login: user.fortinet
   Password: ***********
   Login incorrect

The remote auth with LDAP credentials succeeds when a connection is established with SSH, TELNET, or GUI:

• When the user logs in through the GUI, the FortiADC starts the TCP/389 connection against the LDAP, validating the credentials.
• When the user logs in through the ConsolePort, the FortiADC does not start any connection to the LDAP Server.
  

Issues fixed in the next release:

• v7.6.2.
• v7.8.0.
• v.7.4.7.
